There are no CT scan findings associated with Down syndrome. However, a Multidetector-row CT (MDCT) scan may be helpful in the diagnosis of complications of Down syndrome, which include congenital heart diseases such as atrial septal defect, atrioventricular septal defect, ventricular septal defect, and patent ductus arteriosus.
